This is my first experience with Access Security. The Security was built and applied before the database was split using the wizard. I have moved the back end data to the LAN and plan to put the front end and the mdw file on each individuals PC. This doesn't seem to work because I just checked and I can directly open the back end on the LAN and don't get prompted for a login ID. Do I need to put the mdw file on the LAN also? What did I do wrong? How should this be done?
